3. I have just bought ECO-u1000, how to charge it? Can I charge it as:
1. Charger uses USB2.0 port of PC.
2. Charger uses (5V, 2.0A)
3.Charger uses (5v, 1.8A).
4.Or I have to buy a 5V, 1A charger (like iPhone charger)?
You can charge ECO-u1000 by the PC USB port or a charger with 5V, 1A.
If you use an incorrect charger, it might cause the ECO-u1000 to burn.
It should be fully charged after 8 hours unless the power bank has been used over 500 times charge/recharge cycle. Then the battery efficiency may decline and it cannot be fully charged.
Unfortunately, we do not provide technical manuals to end users, you can contact customer support for assistance.
